DBA 5000 series Crossed Drilled & Slotted 2-Piece Gold Hat DBA52321GLDXS (2 pcs)

DBA Street Series Rotors – Upgraded Cooling, Superior Performance

Ideal for enthusiasts seeking an upgrade over stock rotors, DBA’s Street Series rotors offer premium performance and reliability through innovative design and engineering.

The non-directional cross-drilled and slotted pattern increases the number of outgassing exit points, allowing brake pad friction gases to escape more efficiently. This improves pad bite and reduces fade, especially during high-temperature braking.

Kangaroo Paw Ventilation System

• Features 144 diamond and tear-drop shaped pillars
• Up to 59.7% increase in surface area for superior heat dissipation
• Almost 10% greater mass than standard designs – reduces brake fade
• Even pillar distribution minimizes rotor distortion
• Controlled casting quality for enhanced durability

CBN Machining for Smooth Braking

• Cubic Boron Nitride (CBN) machine-turned finish
• Reduces Disc Thickness Variation (DTV)
• Improves parallelism and minimizes brake shudder

While the 4000 XS Series with T3 slot and cross-drilled design is a great alternative for show cars and open-wheel setups, we recommend the T3 slot design for more intensive performance applications.
